Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

First and foremost, Ukraine’s priority is winning the war and ensuring the safety and security of its people. Ukraine is facing a harsh winter and needs urgent aid and solutions including power generators, heating, and temporary housing to withstand freezing temperatures, ice, and snow. In additio...n to emergency support, the prime focus of Ukraine’s Western partners needs to be on military and economic aid to ensure Ukraine’s victory against Russian aggression and to support its economy in a time of war.

Since late August 2022, cases of severe acute watery diarrhoea have been increasingly reported across Syria, concentrated
particularly along the Euphrates river. These were later confirmed to be cholera cases.3 Cholera is a disease caused by
bacteria that can be found in faeces, and spreads throug...h people consuming contaminated water or food. It causes severe
watery diarrhoea and vomiting which lead to dehydration. If treated immediately, less than 1% of cases result in patients
dying. However, if timely treatment is not available, cholera can lead to death within hours in 25 to 50% of cases. The
situation is critical in Syria as the local population is facing a severe water crisis due to drought, falling groundwater levels,
reduced flow in the Euphrates River, and reduced functionality of Alouk water station. REACH has been monitoring
developments in Northeast Syria through regular data collection cycles, remote sensing data, and rapid needs assessments

Travailler avec les dirigeants communautaires pour lutter contre la VBG est une très bonne et prometteuse approche, car les dirigeants communautaires sont les gardiens de toutes nos croyances et coutumes. Étant donné que la VBG est enracinée dans les croyances et les coutumes, essayer de s...attaquer à la VBG sans impliquer les dirigeants communautaires peut mener à un grand conflit, et vous n’aurez aucun résultat. Les dirigeants communautaires ont également des rôles à jouer dans la réponse aux survivantes de la VBG. Les survivantes s’adressent aux chefs de villages pour faire part de leurs préoccupations et de leurs expériences, et les dirigeants ont des pratiques pour traiter les préoccupations et une approche de la justice qui se base d’abord sur le maintien de la cohésion sociale, mais la VBG ne peut pas être résolue comme n’importe quel autre conflit. D’après mon expérience des programmes de VBG dans mon propre pays et ailleurs, j’ai appris qu’il est plus difficile d’impliquer les dirigeants communautaires dans certains endroits que dans d’autres. Parfois, les aspects religieux rendent les choses plus difficiles. Mais si vous demandez à n’importe quel dirigeant de décrire ce qu’est un dirigeant, ce qu’un dirigeant fait, il parlera de la protection de la communauté. Et c’est aussi ce que nous voulons — protéger les femmes et les filles dans la communauté.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga...s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

Chagas is a complex, multidimensional phenomenon in which political, economic, environmental, biomedical, epidemiological, psychological, and sociocultural factors intersect. Nonetheless, the hegemonic conceptualisation has long envisioned Chagas as primarily a biomedical question, while ignoring or... downplaying the other dimensions, and this limited view has reinforced the disease’s long neglect. Integrating the multiple dimensions of the problem into a coherent approach adapted to field realities and needs represents an immense challenge, but the payoff is more effective and sustainable experiences, with higher social awareness, increased case detection and follow-up, improved adherence to care, and integrated participation of various actors from multiple action levels. Information, Education, and Communication (IEC) initiatives have great potential for impact in the implementation of multidimensional programs of prevention and control successfully customised to the diverse and complex contexts where Chagas disease persists.

Revised and expanded version of the Guidelines
Schistosomiasis is widely recognized as a disease that is socially determined. An understanding of the social and behavioural factors linked to disease transmission and control should play a vital role in designing policies and strategies for schistosomiasis prevention and control. To this must be a...dded the awareness that schistosomiasis is also a disease of poverty. It still survives in poverty-stricken, remote areas where there is little or no safe water or sanitation, and health care is scarce or non-existent. For a variety of complex reasons, many of which are addressed in this book, the disease is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural China. This concern for human behaviour in an environment of poverty echoes the concerns of the new research priority for “diseases of poverty” identified by the Special Programme for Research & Training in Tropical Diseases.

Theodor Bilharz, a German professor of anatomy and chief of surgery at the Kasr El Ani Hospital of Cairo from 1850, first identified an infective organism, Distomum hematobium in 1851, which was renamed Schistosoma haematobium in 1858. It arose from a cestode worm, Hymenoleptis nana, lying in the sm...all colon of an Egyptian patient. He also discovered a trematode worm at the same time from an autopsy, thought to be the cause of urinary Schistosomiasis. Bilharz died from typhoid fever in 1862 at the age of 37. The Theodor Bilharz Research Institute in Giza, Egypt, stands as a tribute to him today. F. Milton published the first recorded peer-reviewed article report on Schistosomiasis in 1914.

This was a Phase 3, multi-center, randomized, open-label, parallel-group, active control study where 273 male and female patients with first stage Trypanosoma brucei gambiense HAT were treated at six sites: one trypanosomiasis reference center in Angola, one hospital in South Sudan, and four hospita...ls in the Democratic Republic of the Congo between August 2005 and September 2009 to support the registration of pafuramidine for treatment of first stage HAT in collaboration with the United States Food and Drug Administration. Patients were treated with either 100 mg of pafuramidine orally twice a day for 10 days or 4 mg/kg pentamidine intramuscularly once daily for 7 days to assess the efficacy and safety of pafuramidine versus pentamidine. Pregnant and lactating women as well as adolescents were included.
